NAME
Crypt::OpenPGP::Words - Create English-word encodingsSYNOPSIS
use Crypt::OpenPGP::Words; my @words = Crypt::OpenPGP::Words->encode( $cert->fingerprint );
DESCRIPTION
Crypt::OpenPGP::Words provides routines to convert either octet or hexadecimal strings into a list of English words, using the same algorithm and biometric word lists as used in PGP (see AUTHOR & COPYRIGHTS for source of word lists).In PGP this is often used for creating memorable fingerprints, the idea being that it is easier to associate a list of words with one's key than a string of hex digits. See the fingerprint_words method in Crypt::OpenPGP::Certificate for an interface to word fingerprints.
USAGE
Crypt::OpenPGP::Words->encode( $octet_str )
Crypt::OpenPGP::Words->encode( $octet_str )
Given an octet string $octet_str, encodes that string into a list of English words.
The encoding is performed by splitting the string into octets; the list of octets is then iterated over. There are two lists of words, 256 words each. Two-syllable words are used for encoding odd iterations through the loop; three-syllable words for even iterations. The word list is formed by treating each octet as an index into the appropriate word list (two- or three-syllable), then adding the word at that index to the list.
Returns the list of words.
Crypt::OpenPGP::Words->encode_hex( $hex_str )
Crypt::OpenPGP::Words->encode_hex( $hex_str )
Performs the exact same encoding as encode; $hex_str, a string of hexadecimal digits, is first transformed into a string of octets, then passed to encode.
Returns the list of words.
